Miscellaneous SCAM work

[JulioTBacmeister]

Would like to have:
-WACCM/WACCM-SC capability for SCAM
-full Slab-ocean / land model capability
-direct computation of dynamical tendencies fro reanalysis + nudging using fields on FV SE grids

Do we need to consider the T42 issue? As don't we have to always interpolate from a FV simulation for a global .i. file. Also what happens with the land for this. And what would be required for SE vertical advection? Do we even care?

[JulioTBacmeister]

I think we should consider the T42 issue for both the land and ocean coupler. At the moment for example SCAM will work with a topography file on any grid (finds the nearest point to scmlon,scmlat) which is very helpful. It would be nice if the coupler would also let us use non-T42 ocean/land grids with SCAM.

As far as the vertical advection I think we should have the capability to use FV/SE's remapping in SCAM.

I'd like to revisit the reanalysis forcing/nudging question from October. My code is more mature now, and I'd like to discuss incorporating it into SCAM.

@JulioTBacmeister and @jtruesdal is this the right issue to discuss moving SCAM testing from Eulerian T42 to a FV grid? I CTSM we want to remove the need for T42 as quickly as we can...
